Do Gardeners' Question Time producers need to weed out any problems? Photograph: Alamy

It first went on air in 1947 and has had garden enthusiasts hooked ever since, but Radio 4's Gardeners' Question Time is now, according to one former presenter, "a pathetic shadow of its former self". Writing in the Daily Mail, Stefan Buczacki, who appeared in 600 episodes, said the show was now too long, lacked a sense of place and had let production values slip.

Are you an avid listener, or is the theme tune your signal to switch off? If you were producing the show, what changes would you make to it, particularly if you wanted to attract a new generation to the joys of gardening?
